Dumb question, when you upload your setup that is what will be used when you turn on your car correct? You don't need to select a certain profile on the ESC itself do you?

What if you need to make changes without a PC at the track. Does that kick the profile back to quick tune so you need to change all the parameters again on the ESC?

You don't set anything once youre locked and loaded on the hotwire, just recalibrate to your transmitter.

You can't make changes at the track without a PC. If you do, or you reset the esc, it will go back to factory default, which is dual mode (you may already be in that..
You also can't adjsut things like turbo etc without a PC

Actually, you can make changes to the ESC via the ESC without affecting the hotwire settings as long as you don't change the motor type. Once you change the motor type it will reset to factory default.

+1 to what catch said.

Just don't change your motor type. I change my drag brake all the time on my esc.

My bad. Didn't realise that could be done
